Chapter 2 Study Guide. Energy enters the ecosystem from the sunlight where organisms known as producers convert it into food. Energy Roles Producers : Take in carbon from the air and through photosynthesis make sugar for its food and release oxygen into the air.

Always starts the food web
The amount of energy available decreases as you move up the pyramid. This means there are fewer animals at the top of the pyramid.
A FOOD CHAIN is a series of events in which one organism eats another to obtain energy.
Condensation: Gas cools and turns back into liquid.
Precipitation: droplets get heavy and drop to the earth as rain, snow, sleet or hail.
Evaporation: water molecules absorb heat from the sun and change to a gas.
Matter in an ecosystem is recycled because the supply is limited while need for it is not.
Producers take in carbon from the air and make C6H12O6 (sugar) for their own food through photosynthesis
Producers release oxygen into the air through photosynthesis.
A biome is a group of ecosystems with similar climates and organisms.
A Biome is determined by climate (temperature and amount of precipitation) because it limits the distribution of plant life.
Climate: the typical weather pattern
There are 6 major types of land biomes
5. Boreal forest
6. Tundra/mountain and ice
